triggerStates	back to summary
private final PseudoClassState triggerStates A Set of all the pseudo-class states which, if they change, need to cause the Node to be set to UPDATE its CSS styles on the next pulse. For example, your stylesheet might have: `.button { ... } .button:hover { ... } .button .label { text-fill: black } .button:hover .label { text-fill: blue }` In this case, the first 2 rules apply to the Button itself, but the second two rules apply to the label within a Button. When the hover changes on the Button, however, we must mark the Button as needing an UPDATE. StyleHelper though only contains styles for the first two rules for Button. The pseudoclassStateMask would in this case have only a single bit set for "hover". In this way the StyleHelper associated with the Button would know whether a change to "hover" requires the button and all children to be update. Other pseudo-class state changes that are not in this hash set are ignored. * Called "triggerStates" since they would trigger a CSS update.

private final PseudoClassState triggerStates

A Set of all the pseudo-class states which, if they change, need to cause the Node to be set to UPDATE its CSS styles on the next pulse. For example, your stylesheet might have:


.button { ... }
.button:hover { ... }
.button *.label { text-fill: black }
.button:hover *.label { text-fill: blue }

In this case, the first 2 rules apply to the Button itself, but the second two rules apply to the label within a Button. When the hover changes on the Button, however, we must mark the Button as needing an UPDATE. StyleHelper though only contains styles for the first two rules for Button.

lookup

back to summary

private CalculatedValue lookup(final Styleable styleable, final CssMetaData<S extends Styleable, V> cssMetaData, final StyleMap styleMap, final Set<PseudoClass> states, final Styleable originatingStyleable, final CalculatedValue cachedFont)

The main workhorse of this class, the lookup method walks up the CSS style tree looking for the style information for the Node, the property associated with the given styleable, in these states for this font.

lookupFont	back to summary
pack-priv CalculatedValue lookupFont(final Styleable styleable, final String property, final StyleMap styleMap, final CalculatedValue cachedFont) Look up a font property. This is handled separately from lookup since font is inherited and has sub-properties. One should expect that the text font for the following would be 16px Arial. The lookup method would give 16px system since it would look only for font-size, font-family, etc only if the lookup on font failed. Text text = new Text("Hello World"); text.setStyle("-fx-font-size: 16px;"); Group group = new Group(); group.setStyle("-fx-font: 12px Arial;"); group.getChildren().add(text);
